Lenzi vs Claude

Claude is a great writing partner.
Lenzi is a charting partner.

If you have built a Claude prompt library for technical analysis, you have been working around a missing capability. Lenzi removes the workaround. The chart is the input.

Dimension
Claude (screenshot)
Lenzi (live chart)
Sees the chart you are viewing
No - only screenshots you upload
Yes - reads the candles on the chart you are viewing
Reads OHLCV data
No - vision model on a flat image
Yes - direct from Polygon.io
Computes levels and structure
Inferred from pixels
Detected from the actual price series
Draws on the chart
Returns text descriptions
Trendlines, zones, markers - directly on the candles
Knows your indicators
Only if you describe them
Sees the SMA, EMA, RSI, MACD, ATR you have on
Memory of your setup
Project context, but no chart access
Sees every prior drawing and the current chart state
Workflow friction
Screenshot - upload - describe - wait
Ask. Done.

Your prompts shrink

You stop describing the chart.

When the AI already sees the candles, the timeframe, and the indicators, you do not need a paragraph of setup. You just ask.

Claude prompt

“Here is a chart of SPY 1H. Volume is in the panel below. Please identify the key support and resistance levels, considering volume confirmation, and tell me where my long thesis would be invalidated...”

Lenzi prompt

“Challenge my long thesis.”

Claude prompt

“Attached is the SPY daily. I have drawn a trendline from the March low. Can you assess whether this trendline is still respected, and whether the recent pullback to the 21-EMA holds...”

Lenzi prompt

“Is the trendline still valid?”

Built for the AI-native trader

The thing you have been trying to hack together.

Live chart context

Every candle, every indicator, every drawing - read by the AI without an upload step.

Drawings as output

Trendlines, zones, and markers appear on the chart, where they belong - not in a paragraph.

Multi-turn analysis

Refine the read in conversation. The AI keeps the full chart state in context across turns.

Common questions

Can Claude read charts from screenshots?+

Claude can describe what it sees in an uploaded image, but it cannot read the underlying OHLCV data. It does not know the exact timeframe, the volume at each candle, or any indicator values. Lenzi reads all of that natively, from the chart you are viewing.

I have a Claude prompt library for chart analysis. Why switch?+

Your prompt library is doing the work of hacking around a missing capability - getting Claude to behave like it can see the chart. Lenzi removes that hack. The chart is the input. The drawings are the output. Your prompts become one-liners.

Does Lenzi use Claude under the hood?+

Lenzi uses Anthropic Claude as its reasoning model. The difference is everything around it - the market data pipeline, the structure-detection engine, the chart-drawing tools, and a workspace built specifically for technical analysis on US equities and ETFs.

Delete the prompt library.

The AI is inside the chart now. Just ask.
